(response options: underweight, a little underweight, about the right weight, a little overweight, or overweight) and selected a sketch that most resembled their children. Participated 418 mothers. The body mass index of mothers and children was calculated. Results: Applying the question, 79.66% of risk of overweight children mothers and 92.95% of overweight children mothers, under estimated their kids' body weight. Using the sketch, 37.29% and 18.51% of mothers of risk of overweight and overweight children respectively, under-estimated the body weight.
